OEM Part - Pondmaster 36(A) 3600gph Complete Replacement Impeller Assembly for Pond-Mag, Mag-Drive Model 36A
NOTE: To determine which Impeller you should refer to the sticker label on the cord-side of the pump. A second method to determine which pump you have is to remove the impeller and inspect the bottom of the cavity. If the pump contains a fitted bearing at the bottom of the impeller cavity then you have a version A, if you DO NOT see a bearing then your pump is likely version B.
PONDMASTER SERVICE is authorized to convert your model 36(A) PUMP to a fit a model 36(B) IMPELLER. This will become necessary very soon as impeller #12790 will no longer be available once current supplies are depleted.
